BOILER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 367,481, dated August2, 1887.

Application filed September 4, 1886. Serial No. 212,705. (No model.)

To aZZ whom it may concern:

Be it known that 1, CHARLES H. WATERoUs, Jr., of Brantford, in thecounty of Brant, Province of Ontario, and Dominion of Canada, haveinvented certain new and useful Improvements in Boiler Attachments; andI do hereby declare that the following is a full,-

- thereof, an outwardly-flaring feeding-chute, a

perforated frame and shield by means of which said box or chamber isattached to the boiler and the rivets and shell of the boiler protected,and of certain other details, hereinafter described. 1

In the accompanying drawings like letters refer to the same parts inboth figures.

Figure 1 is a side elevation. Fig. 2 is a vertical section.

Myimproved device is particularly designed for use with portableengines, and is especially useful in connection with farm-engines forburning straw.

Referring to the drawings, A represents a portion of an upright orVertical flue-boiler to which my furnace attachment is applied.

B is the straw-burner or combustion-chain ber, preferably composed oftwo corrugated cast-iron side sections secured together at the top bybolts passing through the ears b 1), formed upon their contiguous edges,of the sheet-iron end section, N, riveted thereto,

and the bottom H, made of longitudinally-corrugated cast-iron plates,which rest upon lugs h h, formed upon said side sections, as seen inFig. 2. p

The end of chamber B next to the boiler A is open, and the shell of theboiler is cut entirely away adjacent thereto, so as to form anunobstructed opening for the flame and heat to pass from said chamberinto the fire-box of said boiler.

D is a cast-iron door-frame, provided at each side with perforated ears(:5 d, by means of which it is bolted to the boiler, and withvertically-perforated cars a a, corresponding with ears 6 a, formed onthe side sections of chamber B. By means of rods 0, passing through saidears a and c, as shown in Fig. 1, said chamber B is attached to theboiler, and may be readily removed therefrom when it is desired to usethe engine as a wood-burner or for any other purpose. The frame D iscurved over the rivets about the door-hole, and extends slightly throughthe opening into the boiler, thus protecting the shell and rivetingabout said door-hole from the flame and heat, which at that point isquite intense.

Perforations n a, formed in the frame D, just outside of the walls ofchamber B, admit fresh air, which prevents said frame and the adjacentparts from being overheated.

A brace, L, attached to the boiler and the outer end of the chamber B,supports the latter at that point.

To the outer end and. near the top of chamber B is attached thefunnel-shaped or outwardly-flaring feeding-chute G, which is pro vidcdwith a door, 0. Underneath the feeding-chute G, at the bottom of chamberB, is a door, F, by means of which the ashes may be removed from saidchamber and the draft of the burner regulated if desired.

An inclined perforated plate, G, supported just underneath chute 0inside of chamber B upon lugs g 9, cast on the side sections of saidchamber, prevents the straw or other fuel as it is fed into the burnerfrom falling immediately, before it is ignited, to the bottom of saidchamber B. A similar perforated plate, I, placed in an upright positionacross the lower part of chamber B, adjacent to its opening intobOllGf-A, and retained in place by lugs i i, prevents the fuel and ashesfrom working out of the burner into the boiler.

In practice I find that the most satisfactory results are attained withthe least labor by leaving the door 0 of the feeding-chute 0 open andkeeping said chute constantly filled with straw, by crowding thatalready in the chute, whenever the fire needs replenishing, into chamberB with a fresh forkful or supply, which takes its place and closes theOpening into the burner. The outside air is thus prevented from enteringthe burner and from passing thence into the boiler and cooling theflues, which is an unavoidable consequence when the door 0 is opened andclosed and the fuel thrust at the outset entirely into said chamber B.The funnel shape of the feedingchute retains the straw therein until -itis forced into the burner by a fresh supply. As the fuel enters chamberB, it falls upon the inclined plate G, is ignited by the fire below,andfalls over the edge of said plate to the bottom of said chamber B, awayfrom the door F. The flame, heated gases, smoke, 850., pass freelythrough the open end of the burner into the boiler, the plate Iretaining the fuel and ashes in chamber B. V

The details of my improved burner attachmentmay be modified in variousways without departure from the spirit of my invention.

I claim 1. The combination, with astcam-boiler, of anauxiliarycombustion-chamber having the end by which it is attached to said boilerentirely open, substantially as and for the pur poses set forth.

2. The combination, with a steamboiler, of an auxiliary combustionchamber attached thereto and opening into its fire-box, and 'afunnel-shaped feeding-chute attached to said auxiliarycombustion-chamber and opening 7 into the upper part thereof,substantially as and for the purposes set forth.

3. The combination, with a steam-boiler, of a combustion-chamber havingcorrugated walls attached thereto and opening into the fire-box of saidboiler, and a feeding-chute opening in the outer end of said combustionchamber, substantially as and for the purposes set forth.

4. The combination, with a steam-boiler, of the chamber B, attached tosaid boiler and open at the end adjacent thereto into the same, and theperforated frame and shield D, sub stantially as and for the purposesset forth.

5. The combination, with a steam-boiler, of the chamber B, attached tosaid boiler and opening into. the same at the end adjacent thereto,feeding-chute O, and plate G, substan tially as and for the purposes setforth.

6. The combination, with a steam-boiler, of the chamber B, attached tosaid boiler and open into the same at the end adjacent thereto,feeding-chute O, and plate I, substantially as and for the purposes setforth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
